## Abstract

A device is for removing an acetabular cup. The device may include a central body having a first end integrally connected to the central body, bearing a handle, and a transverse handle, and a second end integrally connected to the central body. The device may include a first toothed element, and a second toothed element coupled so that the second toothed element is configured to rotate by the first toothed element when the first toothed element rotates in a previously defined direction.

## Claims

### Claim 1

A device for removing an acetabular cup, the device comprising:
a central body having
a first end integrally connected to said central body, bearing a first handle, integrally and coaxially provided at said first free end of the central body, and a second handle attached to said first handle, said second handle being transverse to a central axis of the central body, and
a second end integrally connected to said central body
a first toothed cup-shaped element, integral with the second end of the central body;
a second toothed element, arranged in front of said toothed cup-shaped element, complementary to said toothed cup-shaped element and substantially symmetrical with respect to one of its central axes, wherein the first tooth cup-shaped element and the second toothed element are detachably couplable to one another and, when coupled, rotation of the first tooth cup-shaped element in a predetermined direction causes rotation of the second toothed element;
a cutting element; and
a stop element which can be detachably coupled to the second toothed element.

### Claim 2 (depends on 1)

The device for removing an acetabular cup as claimed in claim 1 wherein at least one of said first toothed cup-shaped element and said second toothed element has a central axis which does not coincide with the central body.

### Claim 3 (depends on 1)

The device for removing an acetabular cup as claimed in claim 1 further comprising a cutting element and a stop element which can be detachably coupled to a shaft.

### Claim 4 (depends on 1)

The device for removing an acetabular cup as claimed in claim 1 wherein the first toothed element is selectively movable between a first rest position and a second meshed position.

### Claim 5 (depends on 1)

The device for removing an acetabular cup as claimed in claim 1 further comprising an elastic means arranged between said first toothed cup-shaped element and the second toothed element.

### Claim 6 (depends on 1)

The device for removing an acetabular cup as claimed in claim 1 wherein the central axes of said central body and of said end are arranged so as to form an angle of between 0 and 90 degrees.
